PINCE-NEZ.

Specification of Letters Patent.

Patented Mar. 19, 1912.

Appllcation flled May 19, 1511. Serial No.,28,223.

To all whom it may concern:

Be it known that I, ALFRED RICHARD Wan- TER, a subject of the King ofGreat Britain,

and resident of 2 Fordhook avenue, Ealing,

, fication.

This invention relates to improvements in mounts for pince-nez of theso-called frameless type, of the kind wherein the lenses are connectedto the bridge and plackets by means of lens-carriers each consisting ofa pair of oppositely directed spring-arms 1ntegral with the bridge andcurved to extend around the inner end of the corresponding lens at therear side thereof; each carrier being secured to'its lens by means ofclaws ,situatedat and between the extremities of the arms and adapted toclip over the edge of the lens, the end claws being sprung intoengagement with notches in the periphery of the lens. I

The mainobjects of the present invention are to simplify theconstruction of mounts of this kind, to enable. soldering to bedispensed with for securing the various parts together, and to permit oflenses of different thickness being accommodated alternatively suitablybent, the plackets themselves being of what may be called thesli pertype wherein each has an eye at the ack to receive the upwardly bent endof the wire by which it is supported. Each lens-carrier is formed from aseparate length of wire secured to the bridge-wire by meansof rivets,while the middle claw for holding the lens consists of a separate piecefixed to the lenscarrier by the' same rivets which serve to secure thelens-carrier itself to the bridgewire: The claws at the extremities ofeach lens-carrier are readily adjustable ,to suit the thickness of thelens, each claw consistingof a headed pin adapted to engage in thecorresponding notch in the periphery of the lens and screw-threaded topass through a tapped hole provided in the lens-carrier so as to permitof the headof the screw being made to bear against the surface of thelens.

In the accompanying drawings, Figure 1 is a general view of a pair ofpince-nez with the improved mount in its preferred form,

as seen from the rear. Fig. 2 is an enlarged detail view of theleft-hand lens with its carrier, placket, and the corresponding portionof the bridge, also as seen from the rear. Fig. 3 is a plan View, andFig. 4 an inside end elevation of the same parts. Fig. 5 shows thebridge-wire in the flat, 2'. a. before beingbent to its final form. Fig.6 is a similar view of one of the lens-carriers, and Fig. 7 is aseparate view of one of the middle claws of the lens-carrier, also inthe flat.

As will be seen on comparing Fig. 5 with Fig. 1, and with Figs. 2 and 4,a single length of spring-wire serves to constitute the bridge and thetwo placket-holders, this wire being suitably bent, flattened out, andpierced where necessary.: The middle ortion a of the wire forms thebridge, while the adjacent portion 6 toward each end-is bent downwardlyand so curved as to be adapted to lie in contact with the bow of thecorresponding lens-carrier c. The extremities of the wire are upwardlybent to constitute horns cl capable of receiving the plackets e each ofwhich is provided at the back with a projection f pierced by an openingto form a socket or eye through which the upwardly extending extremity dofthe wire is passed, the wire being slightly tapered or bent so as tobecome securely wedged in the socket when thrust therethrough. The twoplackets e, e converge upwardly, and are virtually spring-mounted inconsequence of the elasticity of the wire-ends d, cl which carry them.

Those portions 5, b of the bridge-wire which lie in contact with thebows of the respective lens-carriers c are riveted to the latter, therivets g which secure each carrier to the bridge-wire serving also tofix thereto the base it of the corresponding claw j which isintermediate of the end claws with which each lens-carrier is furnished.Inasmuch as the carrier is placed at the rear side of the lens is, thismiddle claw j is so bent as to clip over the front of the lens and holdthe same against the carrier, the claw itself extending obliquely withreference to the general plane of the lens so that the edge of thelatter, whatever its thickness, will become wedged between the carrier 0and the claw Each lens-carrier constitutes what may be called a semi-rimfor the corresponding lens,

and is formed (see Fig. 6) of a length of spring-wire suitably curved,and flattened out at or about the middle of its length to receive theholes for the rivets 9 whereby it is secured to the bridge-wire and thebase it of the claw j just described.

The claws at the extremities .of each lenscarrier 0 are constituted byheaded pins Z which are screw-threaded to pass adjustably through tappedholes in the carrier in position to engage the notches in the peripheryof'the lens k, each pin Z extending at right angles to the general planeof the lens so that the head m of the pin can be caused to engage withthe outer surface of the lens in such manner as to hold the latteragainst the carrier, whatever the thickness of the lens, by simplyscrewing the pin Z more or less through its hole in the carrier.

Claims:

1. In pince-nez of the kind referred to, the combination of a bridge, alens-carrier on said bridge, a lens carried by said lenscarrier, aseparate claw located intermediate of the ends of said lens-carrier andarranged to exert pressure on one face of said lens,

and fastening means common to said bridge, 1

lens-carrier and claw for securing these elements together.

.carrier on said bridge and located entirely within the periphery ofsaid lens and clamping means on said lens-carrier for exerting apressure on the one face of said lens toward said lens-carrier.

4.111 pince-nez of the kind referred to, the combination of a bridge, alens-carrier on said bridge, a lens, clamping means movably mounted onsaid carrier adjacent to each end thereof for securing'lenses ofdifferent thickness on said carrier and resilient means located on saidcarrier intermediate of said clamping means and engaging sa1d lens.
